WIRE-BINDING- TOOL.

Application filed Apri1 1, 1918.

To all whom it may concern:

Be it known that I, LLEWELLYN DAVIES, a citizen of the United States,and a resident of Sisson, Siskiyou county, State of California, haveinvented a certain new and useful lVire-Binding Tool, of which thefollowing is a specification.

The invention relates to a tool for drawing a binding wire taut on apackage or bundle and for securing the ends of the wire together.

An object of the invention is to provide a hand tool for securing a tautbinding wire to a package or bundle.

Another object of the invention is to provide a hand tool provided withmeans for drawing the wire taut and clamping the ends together, so thatthey may be readily twisted together and with means for subsequentlycutting the wires adjacent the twist.

The invention possesses other advantageous features, some of which, withthe foregoing, will be set forth at length in the following description,where I shall outline in full, that form of the invention which I haveselected for illustration in the drawings accompanying and forming partof the present specification. In said drawings 1 have shown one form ofthe tool of my invention and a modification thereof, but it is to beunderstood that I do not limit myself to such forms, since the inventionas expressed in the claims may be embodied in a plurality of forms.

Referring to said drawings:

Figure 1 is a side view of one form of tool of my invention.

Fig. 2 is a vertical section through the upper jaw.

Fig. 3 is a plan view of the lower aw and the superposed cutting jaw.

Fig. 4 is a side view of a modified form of tool.

The tool of my invention is particularly useful in tying togetherbunches of shooks or similar or comparable articles. Shooks areordinarily fastened together by wrapping a wire around the bunch and theobject of my invention is to provide a hand tool which may be operatedto pull the wire tight before the ends are twisted together and cut, andto provide means for twisting and cutting the wire. The tool comprises aplurality of levers suitably fulcrumed together which are provided withjaws for gripping the mm and pulling it tlght, hold- Specification ofLetters Patent.

ing it so that a rotation of the tool in the hands will twist the wire,and cutting the wire by the application of increased pressure. Securedto or formed integral with the lever 2, is a jaw 3 which is providedwith means for holding the end of the wire. Formed in the body of thejaw 3 is a downwardly-inclined hole 4 and formed in the lower face ofthe jaw is a groove 5 which curves upward to meet the hole on the rearface of the jaw. The end of the wire 6 is inserted in the hole and thewire is bent through the groove and then upward,

whence it passes over the top of the package to be tied. By forming thejaw in this mannor, the wire is prevented from becoming detachedtherefrom.

Fulcrumed to the lever 2, preferably at a point intermediate the ends ofthe lever 2, is a lever '7 which is provided at its end with an integralor removable jaw 8 which constitutes the lower jaw and which cooperateswith the upper jaw Fulcrumed to the lever 7 adjacent the jaw 8 is alever 9 prorider with a jaw 1,2 which codperates with the lower jaw toclamp and cut the wire. The ends of the three levers lie adjacent eachother so that they may be readily gripped in one hand. The upper face ofthe lower jaw 8 is provided with a groove 13, which is inclined to thefront face of the j aw, and this .e'rcove cooperates with and registerswith the groove 5 on the upper jaw, to form a passage in which the endsof the wire are twisted. The lower is provided with a depression 14:immediately behind its upper face 15 and with a cuttin knife 16 arrangedbehind and forming the rear wall of the depression. The jaw 12 isprovided with a tooth 17 arranged to enter the depression and therebybring the under face of the jaw into contact with the knife. Guides orwings 18 may be arranged on opposite sides of the lower jaw to insurethe proper seating of the upper jaw thereon. The jaws are normally heldapart by suitable springs 21 22 engaging the levers.

The wire is first secured to the upper jaw as stated, is then passedover and around the package or bundle and the free end drawn tightlyinto the groove 13 in the lower jaw. This groove is inclined and theside face 23 of the lever 9 is recessed adjacent the jaw, so that thewire may be drawn tightly through the groove. Holding the wire drawntightly into the groove 13, the levers are then pressed together,drawing the wire ti htly around the package. During this action thelever 9 is first moved with relation to lever 7, bringing the tooth 17into the depression in jaw 8 and firmly clamping the wire therein.Additional pressure then brings the upper and lower jaws together,tightening the wire, and may operate to cause the knife to cut the wire.If this pressure is not sufficient to out the wire, additional pressuremay be subsequently applied. When the upper and lower jaws are broughttogether, the ends of the wire lie together in the grooves 5 and 13 androtation of the tool causes the wires to be twisted together. If thewire is not yet cut, additional pressure i'nay now be applied to cut it.The grip on the tool is then relaxed and the upper jaw raised todisengage the wire end therein.

instead of pivoting the levers 2 and 7 intern'iediate their ends, theymav be hinged at their outer ends as shown in Fig. d, but thisrrangement does not provide the leverage for pulling the wire tight onthe bundle tl the other construction doe The various jaws are preferablymade removable, so that they may be readily replaced when worn.

I claim:

1. A wire binding tool, comprising a pair of pivoted levers, a jaw onthe end of one lever constructed to hold a wire end, cooperating jaw onthe other 16311, and means cooperating with said second jaw for firstclamping the wire thereto and then cutting the wire.

2. A wire binding tool, comprising a pair of pivoted l ves, a jaw on theend of one lever constructed to hold a wire end, a aw on the second.lever cooperating with said first jaw, a knife on said second jaw, athird lever pivoted to said second lei er, a jaw on said third levercol'iperating with the jaw on the second lever and the knife thereon, toclamp and out the wire.

3. A wire binding tool, comprising a pair of pivoted levers, a jaw onone of said levers constructed to hold a wire end, a jaw on the secondlever cooperating with said first jaw and having a groove therein inwhich the wire is disposed, a knife on said second jaw, and meanscooperating with said second jaw to clamp the wire thereto and out saidwire behind the point of clamping.

4t. A wire binding tool, comprising a pair of pivoted levers, a jaw onone of said levers constructed to hold a wire end, a jaw on the secondlever having a groove therein through which the wire is. drawn, ashoulder on said second jaw, a knife on said second jaw spaced from saidshoulder, a third lever pivoted to said second lever, a jaw on saidthird lever adapted to enter the space between the shoulder and theknife to clamp the wire to the second jaw and to cut the wire.

5. In a wire binding tool, a having a groove in its upper face inclinedto the front face of the j aw, a depression formed behind said upperface and a knife arranged behind said. depression.

6. A wire binding tool comprising a pair of pivoted levers, a jaw on oneend of one of said levers, said jaw having an opening on the rear facethereof adapted to receive and hold wire end, a jaw on the other leverarranged opposite to and adapted to cooperate with the first jaw andmeans cooperating with the last named jaw for clamping a wire thereto.

7. A wire binding tool comprising a pair of pivoted levers, a jaw on oneend of one of said levers, said jaw having an opening on the rear facethereof adapted to receive and hold a wire end, a jaw on the other ieverarranged opposite to and adapted to cooperate with the first jaw, meanscoo} eratiug with the last named jaw for clamo wire thereto comprising athird lever pivotedto the second named lever and a jaw on said thirdlever cooperating with the jaw on the second lever.

In testimony whereof I have hereunto set my hand at Sisson, California,this zoth day of March 1918.
